Operation
If the minimum allowable cold process fluid temperature is estab- 
Cautionlished at or near minimum heat load, it should be safe for all operat-
ing conditions.
Having established the minimum allowable cold water temperature, maintaining that temperature can be accomplished by fan manipulation, as outlined in Item 4 under Fluid Cooler Operation.

3.As cold air enters the fluid cooler, it causes the falling water to be drawn inward. Thus, under fan operation, the lower periphery of the fluid cooler structure remains partly dry, seeing only random splash- ing from within the fluid
Although ice is unlikely to cause structural damage, it may build up sufficiently to restrict the free flow of air. This effectively reduce the fluid cooler's thermal performance efficiency. When excessive ice forms, stop the fan for a few minutes. With the fan off, the action of the spray system will cause a slight downward movement of air through the coil and deice the fluid cooler.
Intermittent Wintertime Operation:
If periods of shutdown (nights, weekends, etc.) occur during freezing weather, measures must be taken to prevent the water in the cold water
